About the Program
First created in 2011, QuickHash GUI is a graphical data hashing tool for Linux, Windows, and Apple Mac used across the world by government agencies, private industry, media outlets, academia, hobbyists, programmers, training centres, medical scientists, space scientists, operating system developers and maintainers, web developers and more besides. Why? Because it enables the rapid selection & hashing of data such as text, files (either individual files or recursively through a folder tree), text e-mail lists, entire folder trees of files, and disks on all three major operating systems.The user can also compare individual files against one another, or folders of files based on hash algorithms and log the results. This is especially useful when downloading files from the Internet to check the integrity of a file, especially software or operating system distributions like Linux ISOs where it is vital to ensure the downloaded file is the same as that reported to be available by the person\company distributing it.
- it is open source, and
- it is free, and
- it is fast, and
- it is easy to use.
Though it was designed for Linux, is was soon made available for Windows and subsequently Apple Mac OSX (with v2.6.3 in Octo 2015). MD5, SHA1, SHA256, SHA512 available. CSV\HTML\Clipboard output is available which is ueful for verifying hashes of downloaded ISOs like Linux Mint, Ubuntu, Fedora etc.
A source directory can be hashed, then copied & reconstructed to a destination folder where the content is then hashed again (providing verification).
Selected file masks are available (*.doc; *.xls etc) ensuring only certain files are chosen if needed.
Since v.2.4.0 Windows users are able to hash physical disks (SHA-1 only).
LINUX USERS NOTE : The Linux zip contains both 64 & 32 bit versions. Use the correct one for your system – 32 bit won’t work on 64 bit OS and visa versa.
- No DLL’s or installation needed making it portable and easy to run or delete after use.
- A simple non-confusing tabbed interface.
- Cross platform – works the same on Windows, Linux and Apple Mac OSX
- Architecture independent – will run on both 32-bit and 64-bit systems
- Recursive hashing, or hashing and copying to reconstructed directory directory and re-hashing in destination directory.
- Ability to hash segments of text or dynamic hashing as you type into the text field
- Ability to hash files of text line-by-line – useful for those needing to hash lists of e-mail addresses for Google Adwords etc
- Ability to hash disks in Windows and Linux (using root or sudo), e.g. /dev/hda or /dev/hda1
- Simple recursive hashing of all files in a selected directory and its sub-directories with tabulated results as CSV or HTML
- MD5/SHA1/SHA256/SHA512/xxHash algorithms available
- Base64 decoding available (since v2.8.3)
- Enables digital forensic practitioners or IT security staff to hash files at times when files have been extracted out from forensic software before or after transportation to non-forensic staff
- Usually faster than mainstream hashing Windows tools
- Results can be exported to CSV text file, or a HTML web file, or copied to clipboard, or all of those
- Drag and Drop available for individual files
- Full PDF manual with screenshots and explanation of all features.
- No installation. No wizards. No registration. Just double click and use, instantly (or Linxu users can also use Debian packages to install if they wish).
- Open Source (please feedback any code improvements for future versions)
Our History on Sourceforge
QuickHash was first registered on Sourceforge back in 29th May 2011. For a while, it was only used by a selected few who found it useful, but as the features grew and especially when a new interface was created with v2.0 in 2013, it’s popularity soon grew. Used by users of both Linux and Windows, it was downloaded a few hundred times a week at that stage.
Soonafter it became referenced in several books such as ‘Malware Forensic Field Guide for Linux Servers‘ by Cameron Malin, Eoghan Casey, James Aquilina and ‘Investigating Internet Crimes‘ by Todd Shipley and Art Bowker. It was also included in Linux distributions such as DEFT and CAINE.
As of December 2016, the program had been downloaded 136K times from every country in the world except for Antarctica! Weekly downloads were averaging between 2.5K-4K per week. And due to various ethical reasons it was decided that a migration away from Sourceforge was now necessary in favour of the program having its own dedicated website. So the domain name ‘quickhash-gui.org’ was bought and a new server courtesy of Amazon Web Services is now being utilised where the program is now hosted.
Support with the funding costs that are used for the hosting would be welcomed and for that reason some Google adds are displayed on the site to help cover hosting costs (when users click the adds, a few pence comes the way of the developer). If you wish to supply additional donations in support of the project, please do so. If Quickhash has helped you in your work or hobby, a donation would be great to help it continue.
Donations are Welcomed!
If the adverts displayed on the site interest you, then clicking those helps raise a small sum. But better still would be a PayPal donation. You can do that either using the button in the right hand menu (you don’t need a PayPal account to donate using PayPal – just a bank card) or even better, and even faster, by simply navigating to https://paypal.me/quickhash
